Connects your AI agent to official exchange rates from central banks and tax authorities worldwide. You get four tools: fetch latest or historical rates for any supported provider, convert amounts between currencies on any date, list all supported currencies, and discover available rate providers. Authentication is handled via a subscription key header. The same data backs their REST API, so if you're building accounting integrations, ERP systems, or financial reporting tools and need historically accurate official rates instead of market estimates, this plugs straight into Claude Desktop, Cursor, or VS Code. Ask it to convert invoice totals using historical rates or pull specific provider data, and it handles the lookups without any integration code on your end.
